It also recommends raising awareness among policymakers, consumers and the rural poor, and investing to be at the forefront of biodiversity and ecosystems services-based technologies, products and markets. Countries can increase economic benefits by investing and restoring key biodiversity-related sectors such as agriculture, fisheries, forestry, water-related services, protected areas, and tourism, which are crucial for the region’s economy, according to the report. Self-Correcting Fluctuations in temperature and biodiversity are natural – they correct themselves Boulter 2 - professor of paleobiology at the Natural History Museum and the University of East London (Michael, “Extinction : evolution and the end of man,” Columbia University Press, 2002)//JGold Today, world marine life is under threat from overfishing and pollution; naive fish-farming practices have led to dramatic loss in populations. In turn there are effects on the phytoplankton which are crucial in the food chain of all these creatures. It is a curious replay of some of the changes that dominated the land and sea at the end of the Paleocene and set the scene for another 20 million years of high temperatures on our planet. Between 35 and 55 million years ago, Earth saw the peak in diversity of very many animal and plant groups on the land and in the sea. They were relatively tranquil times when the planet was largely at peace with itself, content with the steady rhythms of oscillating temperature, sea level and other environmental changes.¶ Temperatures had been rising steadily since the dinosaur extinction event 20 million years before and flora and fauna flourished to reach a peak in species number. Carbon dioxide concentration in the atmosphere was much higher than today, and without polar ice the sea level as well. Every few tens of thousands of years the river estuaries leading into the North Sea would flood to lay more sediment: the river Thames deposited London Clay from the west, the Seine left deposits from the south around Paris, while the Rhine formed rich sediments in Westphalia. These three ‘rivers’ were not the half- kilometre-wide trickles we know now. Man-made embankments give a deceptive idea of the extent of natural floodplains.¶ The rivers were vast expanses of floodplain, up to hundreds of kilometres across, comprising habitats that ranged from waterlogged marsh to quite shallow water and streaming torrents. The proportion of salt water and fresh water varied according to the different environmental pictures. One of the best permanent exposures of one kind of the resulting sediments, London Clay, is on the northern shore of the Isle of Sheppey, in Kent. On the beach at low tide you can find the fossilised remains of sharks’ teeth, tropical mangrove plants and tropical rainforest lianas.¶ The sea level started to rise and fall through these Eocene times go million years ago, and the oscillations were the first signs of a change ¶ away from the smooth environmental stability since the beginning of the Tertiary. Temperature stopped rising continuously and also began to alternate between highs and lows, rising to a maximum in Europe about 40 million years ago. The low ground between London, Paris and Bonn was at its hottest and tropical rainforest covered much of southern England, Germany and France. As the sea level rose the land bridge separating the London—Paris basin from the Rhine basin became covered with water. Then the sea level fell for another few hundred thousand years to make firm land connections. The land bridge between the British islands and the European mainland rose and fell above these waves. The phenomenon formed cycles that were repeated several times through the 10 million years of tropical heat. Then the climatic oscillations show that it slowly began to get colder.¶ These ideas of climate change in the Eocene of north-west Europe were confirmed in the 1980s by the geological exploration funded by the North Sea oil industry. Thousands of boreholes cored from shallow-water rigs through the clay offshore show cyclical changes in the diversity and concentration of many different kinds of biology. Mollusc and brachiopod shells varied, plankton gave reliable correlations to the same changes, as did pollen from the plants on nearby landmasses. The times of smoothly increasing temperatures were over. At the end of the Eocene, 35- million years ago, cycles of steady global cooling began to show up in the monitoring of climate change. Ocean Biodiversity Increasing Ocean biodiversity is getting better Panetta, 13 – former US secretary of state (Leon, “Panetta: Don't take oceans for granted,” http://www.cnn.com/2013/07/17/opinion/panetta-oceans/index.html)//vivienne Our oceans are a tremendous economic engine, providing jobs for millions of Americans, directly and indirectly, and a source of food and recreation for countless more. Yet, for much of U.S. history, the health of America's oceans has been taken for granted, assuming its bounty was limitless and capacity to absorb waste without end. This is far from the truth. The situation the commission found in 2001 was grim. Many of our nation's commercial fisheries were being depleted and fishing families and communities were hurting. More than 60% of our coastal rivers and bays were degraded by nutrient runoff from farmland, cities and suburbs. Government policies and practices, a patchwork of inadequate laws and regulations at various levels, in many cases made matters worse. Our nation needed a wake-up call. The situation, on many fronts, is dramatically different today because of a combination of leadership initiatives from the White House and old-fashioned bipartisan cooperation on Capitol Hill. Perhaps the most dramatic example can be seen in the effort to end overfishing in U.S. waters. In 2005, President George W. Bush worked with congressional leaders to strengthen America's primary fisheries management law, the Magnuson-Stevens Fishery Conservation and Management Act. This included establishment of science-based catch limits to guide decisions in rebuilding depleted species. These reforms enacted by Congress are paying off. In fact, an important milestone was reached last June when the National Oceanic and Atmospheric Administration announced it had established annual, science-based catch limits for all U.S. ocean fish populations. We now have some of the best managed fisheries in the world. Progress also is evident in improved overall ocean governance and better safeguards for ecologically sensitive marine areas. In 2010, President Barack Obama issued a historic executive order establishing a national ocean policy directing federal agencies to coordinate efforts to protect and restore the health of marine ecosystems. President George W. Bush set aside new U.S. marine sanctuary areas from 2006 through 2009. Today, the Papahanaumokuakea Marine National Monument, one of several marine monuments created by the Bush administration, provides protection for some of the most biologically diverse waters in the Pacific. Marine Resiliency Diversity and resilience refute an all out collapse of marine biodiversity JCU 11 – (“Climate will damage reefs at different rates”, July 22, James Cook University, http://www-public.Jcu.edu.au/news/JCU_083861)//JFHH Climate change and acidifying ocean water are likely to have a highly variable impact on the world’s coral reefs in space, time and diversity, international coral scientists cautioned today. The picture that is emerging from studies of past coral extinctions and present impacts on today’s reef systems is complex and subtle and will demand much more sophisticated management to preserve reefs intact, the team of scientists reports in a paper in the international journal Science. “New research confirms that coral reefs… are indeed threatened by climate change, but that some current projections of global-scale collapse of reefs within the next few decades probably overestimate the rapidity and uniformity of the decline ,” the researchers say. “A considered view of all the most recent evidence suggests that some coral reef systems will decline more rapidly – especially those subject to other human pressures such as overfishing – while others may change in composition, but manage to persist for longer ,” says lead author Professor John Pandolfi of the ARC Centre of Excellence for Coral Reef Studies and the University of Queensland. The paper, “ProJecting coral reef futures under global warming and ocean acidification” by John M. Pandolfi, Sean R. Connolly, Dustin J. Marshall and Anne L. Cohen appears in the latest issue of the journal Science. “Coral reefs occupy a small part of the world’s oceans, yet harbour a hugely disproportionate amount of its biodiversity,” the researchers say. “More than 450 million people from 109 countries live close to coral reefs, which provide important sources of ecosystem goods and services for these communities. “But reefs have suffered degradation from human over-exploitation and pollution over centuries to millennia , degradation that has accelerated in the last 50 years.
